GLPUSHCLIENTATTRIB(3G)													    GLPUSHCLIENTATTRIB(3G)

NAME

       glPushClientAttrib, glPopClientAttrib - push and pop the client attribute stack

C SPECIFICATION

       void glPushClientAttrib( GLbitfield mask )

PARAMETERS

       mask  Specifies a mask that indicates which attributes to save.	Values for mask are listed below.

C SPECIFICATION

       void glPopClientAttrib( void )

DESCRIPTION

       glPushClientAttrib  takes one argument, a mask that indicates which groups of client-state variables to save on the client attribute stack.
       Symbolic constants are used to set bits in the mask.  mask is typically constructed by OR'ing several of  these	constants  together.   The
       special mask GL_CLIENT_ALL_ATTRIB_BITS can be used to save all stackable client state.

       The symbolic mask constants and their associated GL client state are as follows (the second column lists which attributes are saved):

       GL_CLIENT_PIXEL_STORE_BIT     Pixel storage modes
       GL_CLIENT_VERTEX_ARRAY_BIT    Vertex arrays (and enables)

       glPopClientAttrib  restores  the  values  of  the  client-state variables saved with the last glPushClientAttrib.  Those not saved are left
       unchanged.

       It is an error to push attributes onto a full client attribute stack, or to pop attributes off an empty stack.  In either case,	the  error
       flag is set, and no other change is made to GL state.

       Initially, the client attribute stack is empty.

NOTES

       glPushClientAttrib is available only if the GL version is 1.1 or greater.

       Not all values for GL client state can be saved on the attribute stack.	For example, select and feedback state cannot be saved.

       The depth of the attribute stack depends on the implementation, but it must be at least 16.

       Use glPushAttrib and glPopAttrib to push and restore state which is kept on the server. Only pixel storage modes and vertex array state may
       be pushed and popped with glPushClientAttrib and glPopClientAttrib.

       When the GL_ARB_multitexture extension is supported, pushing and popping client vertex array state apples to all supported  texture  units,
       and the active client texture state.

ERRORS

       GL_STACK_OVERFLOW is generated if glPushClientAttrib is called while the attribute stack is full.

       GL_STACK_UNDERFLOW is generated if glPopClientAttrib is called while the attribute stack is empty.
